Stephen Hawking is the world-famous physicist with a cameo in The Simpsons on his CV, but outside his academic field his work is little understood. To the public he is a tragic figure - a brilliant scientist and author of the 9 million-copy-selling A Brief History of Time, and yet confined to a wheelchair and almost completely paralyzed.

Hawking's major contribution to science has been to integrate the two great theories of 20th-century physics - Einstein's General Theory of Relativity and Quantum Mechanics. J.P. McEvoy and Oscar Zarate's brilliant graphic guide explores Hawking's life, the evolution of his work from his days as a student, and his breathtaking discoveries about where these fundamental laws break down or overlap, such as on the edge of a Black Hole or at the origin of the Universe itself.
